Description
Technical field
The application relates to field of papermaking, relates to the forming fabric of using in the papermaking more specifically.
Background technology
In traditional fourdrinier wire papermaking process, the water slurry of cellulose fibre or suspension (just in the papermaking usually said " paper stock ") stream is delivered on the up top, the endless belt of mesh grid and/or synthetic material, and the endless belt operates between two or more rollers.The endless belt is commonly referred to " forming fabric ", and the up upper surface of forming fabric provides papermaking surface to separate the fiber of paper stock as filter from aqueous medium, forms wet web thus.Aqueous medium leaches from the mesh (common name osculum) of forming fabric by gravity or the vacuum action that is arranged at the up lower surface of forming fabric (just " pusher side face ").
Wet web leaves the press section that enters paper machine after the forming part, and paper web is through one or more pairs of nips that are coated with the pressure roller of another fabric, and this fabric is commonly referred to " press felt ".The pressure of roller makes wet web remove other moisture; The removal that the existence of " cotton layer " of press felt has further improved moisture.Then paper is transferred to drying section and further removed moisture.After super-dry, paper is through secondary operations and packing.
As using in this application, term vertically (" MD ") and horizontal (" CMD ") is meant respectively to become the direction of a line with the traffic direction of papermaking fabric in the paper machine and be parallel to fabric face and transverse to the direction of fabric traffic direction.Similarly, relate to the direction of yarn vertical relation in the fabric (for example top, below, top, bottom, under etc.), the paper side of supposing fabric is the top of fabric, and the pusher side face of fabric is the bottom of fabric.
Papermaking fabric normally passes through the endless belt of a kind of manufacturing in two kinds of basic braid methods.In the first method in these methods, fabric is by the method braiding of plain weave, end connects into the endless belt by known method of attachment in the method, end is woven together (being twisted weave) after for example decomposing again or on every end, sews on thin slice that pin can sew up or special folded part, then they are woven into the ring that pin can be sewed up again.Many automatic connection machines are commercially available now, can use this machine to come automation mechanized operation for some forming fabric to small part connection operation.In the plain weave papermaking fabric, warp extends in the vertical, and parallel extends in the horizontal.
In second kind of braid method, fabric directly weaves with the form of continuous band with the annular weaving method.In the annular weaving method, warp extends in the horizontal, and parallel extends in the vertical.Two kinds of braid methods of foregoing description all are existing technology, are meant the ribbon that by any method obtained as the term " endless belt " that uses herein.
Effectively page and fiber support body are important consideration in the papermaking, particularly in the forming part of the paper machine that wet web begins to form.In addition, when high-speed cruising on the paper machine, forming fabric should demonstrate good stable, preferably has high osmosis, reduces the moisture that paper web keeps when transferring to the press section of paper machine with convenient paper web.In tissue paper and fine paper are used the paper of using of senior printing, carbonization, cigarette, capacitor and this type of (promptly), papermaking surface comprises network structure very careful braiding or fine wire.
Usually, the vertical or horizontal yarn that comprises at least some relative minor diameters as the forming fabric of the careful braiding in the application of fine paper and thin paper, used.Yet regrettably, such yarn is fragile often, thereby causes fabric short service life.And the use of less yarn can also negatively influence the mechanical stability (especially aspect asymmetric drag, shrinkage and rigidity) of fabric, and these all may influence the service life and the performance of fabric.
These problems that interrelate for the fabric that solves with careful braiding, developed multi-layer forming fabric, this fabric has the fine mesh yarn on the paper profiled surface so that paper is shaped, and has coarse mesh yarn on machine contact side so that intensity and ABRASION RESISTANCE to be provided.For example, use one group of vertical yarn and two groups of transverse yarns weavings to constitute fabric has the surperficial and more durable pusher side surface of thin sheet forming with formation fabric.This class forming fabric belongs to a kind fabric that is commonly referred to " bilayer " fabric.Similarly, constituted the fabric that comprises two groups of vertical yarns and two groups of transverse yarns, it forms the paper side tissue layer of trickle mesh and the thicker pusher side tissue layer of separation.This class forming fabric normally is called " three layers " fabric, and in this kind fabric, two tissue layer normally combine by independent stitching yarns.Yet they also can use one or more groups bottom, upper lateral and vertical yarn to combine.Because double-deck comparing with woven with treble cloths comprises one group of additional yarn, thereby these fabrics have higher " paper thick (caliper) " (that is, they are thicker) than woven usually.The U.S. Patent No. 4423755 of Thompson has provided a kind of illustrative two-layer fabric, and the U.S. Patent No. 6745797 of the U.S. Patent No. 5437315 of the U.S. Patent No. 5152326 of the U.S. Patent No. 4501303 of Osterberg, Vohringer, Ward and US5967195 and Troughton has all been reported illustrative three formable layer fabrics.
U.S. Patent No. 6896009 and the common unsettled and common U.S. Patent Application Serial Number US11/207 that transfers the possession of that submitted on 08 18th, 2005,277 have described many typical multi-layer forming fabrics, and these fabrics are by " through suturing with thread management ".In some cases, the easier manufacturing of forming fabric that may sew up than parallel of above-mentioned fabrics and/or perfect performance is arranged.Yet the fabric through suturing with thread management that also needs other type satisfies the great demand of paper industry.
